A random access method, an apparatus, and a system are disclosed. A terminal device receives, from a network device, information about a PRACH resource set and information about one or more PUSCH resources associated with each PRACH resource in the PRACH resource set. If a first PUSCH resource associated with a valid first PRACH resource in the PRACH resource set is valid, the terminal device sends a first preamble sequence to the network device on the first PRACH resource, and sends uplink data to the network device on the first PUSCH resource. The network device receives the first preamble sequence from the terminal device on the first PRACH resource, and receives the uplink data from the terminal device on the first PUSCH resource. The first preamble sequence is a preamble sequence set associated with the first PUSCH resource.
Legal claims defining the scope of protection, as filed with the USPTO.
5. The method according to claim 1, wherein the first PUSCH resource is a resource segment of a second PUSCH resource associated with the first PRACH resource, and the resource segment is used for repeated transmission of a PUSCH.
10. The communications apparatus according to claim 9, wherein the at least one processor is further configured to receive first indication information from the network device via the transceiver, and wherein the first indication information indicates the third threshold.
11. The communications apparatus according to claim 7, wherein the first PUSCH resource is a resource segment of a second PUSCH resource associated with the first PRACH resource, and the resource segment is used for repeated transmission of a PUSCH.
16. The communications apparatus according to claim 15, wherein the at least one processor is further configured to send first indication information to the terminal device via the transceiver, wherein the first indication information indicates the third threshold.
17. The communications apparatus according to claim 13, wherein the first PUSCH resource is a resource segment comprised in a second PUSCH resource associated with the first PRACH resource, and the resource segment is used for repeated transmission of a PUSCH.
